    Plus & Minus Signs

    1 2 3 4 5 6 7 8 9 = 100

    A. Insert 7 plus or minus signs between the digits on the left side to make the equation correct?

    B. Insert 3 plus or minus signs between the digits on the left side to make the equation correct?

    <font color=blue>Note or clarification: Without changing the order of the digits on the left side of the equal (=) sign, simply insert the stated number of plus (+) or minus (-) signs to make the equation true. You don't have to choose one or the other, you may you a combination of plus and minus signs as long as the total number of signs is as stated.
    An example of an incorrect solution to puzzle A would be: 1 + 2 - 3 + 45 + 6 + 7 + 8 - 9 = 100
